Hi Guys,
Finally today I can go back to my office and do some test.
Thanks Doug for providing me the idea.
So here is my test result.
i've used what Doug gave me and printed with Absolute Col rendering intent.
The result is very linear compare to the ideal line, which formed based from the blackest point and the paper white point.
So after this experiment, I have 2 more questions regarding to this:
1st question:
Doug provided me this special target and I understand how does he created this. Basically 21 steps are plot from my ideal numbers from excel.
But when map my black point and white point to a "normal 21 steps" target (0-255), how come I could not get the middle patches RGB number as same as my excel calculation?
For example, on excel sheets, the middle patch RGB number should be 121,121,121, in Photoshop, it will become 131,131,131?
2nd question:
The reason I'm doing this test is because I'm trying do digital negatives.
In theory, a more linear we can get, a better control we could have during the process.
You may not agree but at least this is so far working good with our workflow.
But I doubt it I should use absolute col. rendering intent when I print my digital neg.
What we've been using is Rel Col with BPC on.
The image looks nice but when we print the 21steps target, it turns out not very linear.
So, any ideas?
Of course I'll do some more test on my side, would like to share more and update you guys.
Thanks everyone!
Regard,
Aaron
